HOSE-COUPLING.

SPECIFICATION forming part of Letters Patent No. 248,658, dated October25, 1881.

Application filed August 15, 1881.

To-all whom it may concern Beitknown that 1, PETER LORD, of the city andDistrict of Montreal, Province of Quebec, Canada, have invented certainnew and useful Improvements in Hose-Couplings; and I do hereby declarethat the following is a full, clear, and exact description of the same.

This invention has reference to improvements in hose-couplings to renderthem capa- 0 bio of being connected and disconnected while underpressure, or, in other Words, while a head or column of water is passingthrough one or both of them; it also renders them more easy ofconnection in case of having to couple them together in the dark, and itprevents the crossing of the threads of their screws when great haste isrequired.

In the drawings hereunto annexed similar letters of reference indicatelike parts.

Figure 1 is an elevation of a hose-couplingcompletelyconnectedeinboclyingmyinvention.

Figs. 2, 3, and 4 show one-halfof the coupling separated into itsrespective parts. Fig. 5

shows the other half of the invention with the 2 parts composing it puttogether. .Fig. 6 is a section 'on line at m, Fig. 1.

Letters A and B are the bushes to be attached to the two ends ofhose-pipes to be connected together. On the end surface of A, as

indicated by G, and on the end surface of B, as indicated at D, a groundjoint is formed, so that bringing the two together they are renderedwater-tight withoutany packing, Sac.

()n the outside of the surface forming the joint, as above mentioned, onthe bush A, a

semicircular grooved flan ge, E,is formed, agreeing with a groove, F,and flange G on B, so that it is only necessary to bring the twotogether and place them in the position shown in Fig. 6, so that thegrooved flange E not only serves as a hook to hook the two bushes to-(No model.)

gether, but it also holds them in such relative position that the threadof the nut H will agree with the thread of the collar I on the bush B,and thereby prevent any danger of crossing 5 the threads when screwingup the nut H on the collar I. The surfaces of the nut H and bush A at 0(see Fig. 6) are also preferably got up to a ground joint, so that incase of damage to the surfaces of the ends of A and B the coupling mayyet be tight.

It will be observed that the flange E is provided with holes B. Theseare to allow any water that might lodge in the groove to escape, as inwinter-time it might freeze and retard the free uniting of the bushes.

Although the nut H is provided with projections for the ordinary wrench,yet as a usual thing no wrench will be required, as the nut H may bescrewed up by hand; but for fear of jamming the projections areprovided.

I do not claim any improvement in the manner of attaching the hose-pipesK to the bushes A and B.

What I claim, and wish to secure by Letters Patent is as follows:

1. The combination of the bush A, having flange E, and half 0 of joint,as described, with bush B, having groove F, and half D of joint, flangeG, and collar I, and not H, the whole constructed, arranged, andoperated substantially as set forth.

2. The combination of the bush A, having flange E, as described, withbush B, having groove F, flange G, and collar I, and the not 7 5 H,having joint 0 formed on it and on the bush A, the whole constructed,arranged, and operated substantially as set forth.

PETER LORD.
